is there good tool to analyse some csv-formatted data files. is there any easy to use open source thing to display data from csv-files? (please don't mention excel...). most important is an easy file import (or maybe folder read-out) mechanism.
I found D3 to be the best solution: http://d3js.org/
An excellent tool is Weka. It accepts data in csv as well as arff format. It is free and open source, can be used to visualize as well as to run inbuilt machine learning algorithms to gain more insights into the data.
The best thing is that it is extremely light weight and easy to use, you don't need anything except support for java.
Get it from here. Once started, it looks like :
Now go to Explorer, open file and you are done!
IBM's Many Eyes project is a free web-based collaborative tool that has lots of charts available.
Better, but expensive, are Spotfire and Tableau. Both are amazing commercial applications for this, and Spotfire especially is incredibly easy to use to explore lots of visualizations side-by-side. Both have a desktop version and an online web player (Spotfire demo gallery, Tableau demo gallery). They are both highly scalable, into the millions of rows. Both have free trials.

I'm using mysql for my database needs and the total size is ~1.5 TB.
I'm looking for a Business intelligence tool which gives me an interface to fetch reports in any desired format to help decision making. The user shall be able to sum, sort, count, sum in various ways.
I don't know what shall I do about it.
In the past few days, I've read dozen of articles and watched many videos about Bigdata, hadoop, BIRT, Solr, Cassandra, mongodb, noSql and just everything that popped in search suggestions for my queries on BI but can't decide what's the right tool for me.
Is there a tool available to help me with my Data reporting and visualizing needs?
Did you read about Tableau (http://www.tableausoftware.com/)? Its a very nice data visualization tool (though not free but worth it) and can connect to various data sources (mysql, hive etc). Also it provides options to do all such operations you mentioned. It will be worth to evaluate it once.
It provides a 15 day free version. You can try out and see if it fits your needs.
Try Google Big Query, it should solve your issue

Suggest me any open source based platform/IDE/framework/toolkit for developing intelligent agent. I don't have any background in this area, would like to use a tool or any tutorial in building intelligent agent.
If you don't have any background at all, I suggest you start with something simple.
I had quite a good experience with dmangame, a simple Python engine where you can script the behaviour of agents.
The good point is that the installation is very simple, you know where to code your Python scripts for AI, there is a nice API for it. And you've got a nice graphical interface to see directly what you code.
Edit : By the way, look at this similar question
Weka is probably the most comprehensive open source AI toolkit. It's positioned as a tool for "data mining" but don't let that put you of - it's a general toolset for machine learning which is exactly what you need if you want to build an intelligent agent.
You can use any IDE you like with it (it's Java based so that gives you a range of great open source IDEs such as Eclipse or Netbeans, but you can also call the Weka libraries from other languages if you like).
It also has some of its own tools build it (for visualisation and exploring data sets etc.)

I am looking into creating a simplified version of a CRM without having to reinvent the wheel on some of the base functionality.
Would you please recommend an open source CRM product that I could use?
NOTE: I would be interested in solutions with PHP or Java.
Have you looked at SugarCRM? It's pretty mature so it might not meet your "simplified" qualifier, but if I were in your shoes I'd probably consider starting there. It started life as an open-source project and there is still a "community edition".
Consider, however, that I have little familiarity with CRM in specific, so I can't comment one way or another on the quality of SugarCRM. Good luck.
For me VTECRM 4 is the best! It's based on sugar and vtiger crm and it's easy to use. You can download it and customize. It's based on php - mysql and it's free. dowload link: http://code.google.com/p/vtecrm/source/checkout
If you want a simplifed CRM, SugarCRM is NOT the place to start.
Have a look at Tine2.0. It has a demo online, it's built with PHP and ExtJS (so it feels like a desktop application) and is very easy to modify, and has a sizable community behind it (though the owner had the "vision" to split it by language, so unless you read German well, you'll have to use Google translate most of the time)
It doesn't do Gantt charts, but it does tagging.

Is there any web service to analyze big data sets and plotting graphics like in Excel? I need something simple, efficient and with web GUI.
Google Fusion Table might be a candidate for your choice.
Google Docs also can be your choice, if you just want simple Excel-like graphics.
If you want to have more controll over the analysis (not just using Excel as a table editor), you can try analytic tools like BellaDati (https://service.belladati.com/login). It is still free for personal use.
Google Fusion Table is good for data mining but not analysis and createing charts. Bi software creates good summary charts/pivot tables etc. not scientific charts. What kind of data you want to analyse?
Peter
Web Pivot Table is this kind of tool you could give it a try. It can connect to CSV files or OLAP Cubes and do any pivot operations just like excel. It is web based and totally run inside browsers.
And it is pure javascript implementation which can be easily embedded into any web application as a component.
Here is demo and documents.

I haven't done this in 3 or 4 years, but a client wants to downgrade their dynamic website into static HTML.
Are there any free tools out there to crawl a domain and generate working HTML files to make this quick and painless?
Edit: it is a Coldfusion website, if that matters.
Getleft is a nice Windows client that can do this. It is very configurable and reliable.
Wget can, too, with the --mirror option.
Try using httrack (or webhttrack/winhttrack, if you want a GUI) to spider the web site. It's free, fast, and reliable. It's also much more powerful than primitive downloaders like wget; httrack is designed for mirroring web sites.
Be aware that converting a dynamic page to static will lose you a lot of functionality. It's also not always possible - a dynamic site can present an infinite number of different static pages.
It's been a long time since I used it, but webzip was quite good.
It is not free, but for $35.00, I think your client won't go broke.
A quick google for offline browsers came up with this and this that look good..
